Scag mulching kit

I have a 48 scag ultimate hydro and the mulching plate does not seem to fit correctly.<br>It has predrilled holes in the deck and the plate comes with a bolt, eye bolt, 6 washers, and 3 nuts. The problem I am having is that the holes do not line up. Has anyone else had this problem or am I just doing something wrong?

I have a 48&quot; Scag Super Z and bought the mulching plate also. I had trouble at first but don't know if the decks are designed the same. The front of the plate goes inside the deck and the back fastens outside. If you are doing this it should fit, but then again I dont know if the decks are the same.
